VEHICLE-LAMP.

Specification of Letters Patent.

Patented May 22, 1906.

Application filed March 26,1906. Serial No. 308,075.

g which the following is a specification.

My invention relates to vehicle-lamps, especially such as are used onautomobiles or other vehicles, and has for its object the providing ofnew and improved means for securing'the burner-support or pot to thelampbody, and the invention will be readily understood from thefollowing description and claims and from the drawings, in which Figure1 isa. perspective view of my improved device. Fig. 2 is a sideelevation of the locking means between the burner-support and lamp-body,the burner-support and lamp-body being broken away and shown inseparated relation with the burner entering the lamp-body. Fig. 3 is aside elevation of the same, showing the parts inlongitudinally-associated relation, but priorv to the turning of the potor burner-support for looking the parts..- Fig. 4 is a side elevation ofthe samewith the parts in locked relation. Fig. 5 is a perspective viewof the slot-closing slide. Fig. 6 is a plan view of the pot, showing thelocking pins or fingers. Fig. 7 is a perspective view of the lockingportion of the body, and Fig. 8 is a bottom-view detail in cross-sectionon the line a: so of Fig. 3.

l is the body of the lamp, and 2 is a pot or burner-support to which aburner 8 is secured. The burner has a shaft 4, which in thepresentexemplification of my invention is the wick-shaft of the burner, the potrepresenting an oil-pot. The body is provided with a locking portion,which is at the lower portion of the lamp-body and is shown as a barrel.6, the inside of which preferably has inclined faces 7, upon which pins8 on the pot are adapted to ride for drawing the pot toward the body inattaching the former to the latter. The barrel is provided with recesses9, adapted to permit the insertion of the pins 8 for reception of thelatter upon the inclines 7. The-inclines are preferably formed upon theedges of inturned flanges 10 of the metal, such as sheet-brass, formingthe barrel, thereby forming a channel 11.

12 is a plate rovided with a slot 13, adapted to receive t e shaft 4when the pot is secured to the body and also preferably arranged toreceive one of the pins 8, the shaft being positioned in substantiallyvertical plane with one of said pins in securing the burner to the pot.This plate preferably The barrel is pro slides in the channel 11. videdwith a slot 14, registering with the slot 13 when the pot is movedtoward the body for bringing the burner inside the body.

'When the pot is received by the body, the

pot is arranged to be turned sidewardly, and for permitting thissideward turning the barrel is provided with a sidewardly-extending slot15. The plate at the slot is also preferably provided with flanges 1616, forming side walls for the slot 13 in the plate, adapted to beengaged by the shaft and by the pin in vertical plane therewith formoving the plate sidewardly with the pot in the turning of the pot uponthe body. The sideward positioning of this plate, however, is effectedpreferably primarily by the pin, so as to avoid side stress upon theshaftand avoid the danger of destroying the connection between theburner and pot. The plate is also provided with clamping means clampingthe same to the barrel for locking the pot or burner-support in itsdrawn relation. Thus I have shown a bolt 17 secured to the plate and eX-tending outwardly therefrom in an extension 18 of the slot 15, athumb-nut 19 taking over the bolt and clamping the plate to the barrel.In such clamped position the inner end of the nut preferably takesagainst the upper wall 20 of the slots 15 18 and the tongues 21 22,formed between the slot 14 and the slots 15 18, thereby making anespecially rigid construction, although it is obvious that such clampingmay take place at any point along the sidewardly-eXtending slots,dependent on the position which the pins 8 occupy on the inclines 7 whenthe burner-support has been drawn toward the body.

It will be noted that the combined slots 14 15 18 form an associatedT-slot in the wall of the barrel, and that the late 12 serves'as afilling-plate for covering t ese slots when the parts are in lockedrelation for the exclusion of air-currents from the interior of thelamp, and, further, that the movement of the plate into the unlockedrelation of the securing means is limited by the bolt 17 taking againstthe end wall 23 of slot 18, thereby causing the slots 13 and 14 toregister, and that the movement of the plate into locked relation islimited by the shaft 4 taking against the end wall 24 of the slot 15,this shaft being also sidewardly held against movement by the walls ofslot 13 for maintaining all the parts in correct relation and insuringthat the flame shall always be substantially transverse of the frontface 25 of the lamp.

As already stated, the inside of the barrel is formed with flanges 10.These flanges are preferably annular, The pot or burner-support is alsopreferably provided with an annular wall 26, in which the pins 8 aresecured, the said annular wall being hugged by the flanges 10 when theparts are in assembled relation for definitely centering the burner inthe lamp.

In vehicle-lamps, especially such as are used on automobiles, where theyare subjected to continued and violent vibration and jarring, myimproved device is especially serviceable, as the parts are all held inlocked relation by positive fastening means, and the parts are socorrelated as to make a neat appearance, to prevent detrimental currentsreaching the flame, and to secure the parts rigidly together.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is 1 1. The combination of alamp-body and a burnersupport, the lamp-body and burnersupport havingmating engaging means, the said engaging means arranged to act uponrelative turning between said lamp-body and burner-support, the lowerportion of said lamp-body having a transverse slot and adownwardly-extending slot merging therewith, a plate at said slot, saidplate having a slot arranged to receive the shaft of the burner of saidburner-support, and a clamp extending from said plate through said transverse slot to outside said lamp-body for clamping the parts togetherafter said relative turning between said lamp-body and burner-support.

2. The combination of a lamp-body and a burner-support, the lowerportion of said lamp-body having a downwardly-extending slot andlaterally-projected slots extending from said first-named slot, a platetaking across said slots and having a slot therein adapted to registerwith said downwardlyextending slot in a given position between saidplate and first-named slot, said burnersupport having a part thereonadapted-to take through one of said laterally-extending slots, and saidplate having clamping means thereon extending through the other of saidlaterally-extending slots, substantially as described.

3. The combination of a lamp-body and a burner-support, the lower ortionof said lamp-body forming a seat for said burnersupport, and saidburner-support adapted to be received by said seat and turned therein,

a the lower portion of said lamp-body provided with a T-slot, aplate'adapted to take across said T-slot and having a slot adapted toregister with the downwardly-extending stem of said T-slot, ascrew-clamp on said plate having movement in one of thelaterally-extended wings of said T-slot, the other of said laterallyextended wings of said T slot adapted to receive the shaft of saidburnersupport, substantially as described.

4. The combination of a lamp-body and a burner-support, the lowerportion of said lamp-body formed into a seat having inclined ways, theburner-support provided with pins arranged to travel on said ways, theshaft of the burner of said burner-support arranged to be placedsubstantially vertically of one of said pins, the lower portion of saidlamp-body having a downwardly-extending and downwardly-opening slotarranged to receive said shaft and last-named pin, a plate having adownwardly-extending slot adapted to register with said first-named slotwhen receiving said shaft and pin, the lower portion of said lamp-bodyhaving a sidewardly-extending slot to each side of said first-named slotandmerging therewith, a screw-clamp on said plate, said burner-supportarranged to turn in said seat and thereby move said plate by contact ofsaid lastnamed pin with the wall of the slot in said plate and therebymove said burner-shaft into one of the sidewardly-extending slots andthe screw-clamp in the other of said sidewardly-extending slots and fordrawing said burnersupport toward said lamp-body, said screw-clamparranged to clamp the burnersupport to the lamp-body in drawn position,substantially as described.

In testimony whereof I have subscribed my name hereto in the presence oftwo subscribing witnesses.
